Abstract (en)
A gallosilicate zeolite is prepared by treatment of a high silica gallium-free zeolite with a source of gallium in an aqueous solution having a pH no less than 7 at 50 DEG -250 DEG C. The product is then ammonium-exchanged and calcined to produce a catalyst with increased Bronsted acidity.
